Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a rideable luggage. Background Technology

[0002] While traditional cycling suitcases have solved the need for short-distance commuting, most cycling suitcases on the market currently use a fixed front wheel assembly, requiring users to push off the ground with their feet to assist when turning, resulting in poor riding stability and difficulty in operation; in addition, the rear wheel of traditional suitcases is usually fixed and exposed on the back of the suitcase, which significantly increases the overall thickness and causes the suitcase to take up too much space when checked in or stored.

[0003] Therefore, it is necessary to propose a brand-new type of suitcase that can be easily controlled to turn and adapt to different usage scenarios, thereby improving the user experience. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the suitcase provided by this utility model allows users to easily control the steering and adapt to different usage scenarios, thereby improving the user experience.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] This utility model provides a rideable suitcase, including a suitcase body, a front wheel assembly, and a rear wheel assembly. The interior of the suitcase body forms a storage space for accommodating luggage. The front wheel assembly is located on the front side of the suitcase body and includes a pull rod assembly, a steering mechanism connected to the pull rod assembly, and at least one swivel wheel. The swivel wheel and the steering mechanism are connected by a transmission component. The rear wheel assembly is located on the rear side of the suitcase body and includes a rear wheel. The rear wheel rotates to drive the suitcase to move, and the steering mechanism can be turned by rotating the pull rod assembly, which in turn drives the swivel wheel to turn via the transmission component, thereby controlling the direction of movement of the suitcase.

[0007] As an improvement of this utility model, a storage chamber is also provided at the rear bottom of the box body. The rear wheel assembly is movably disposed in the storage chamber. The rear wheel assembly includes a rear wheel and a mounting bracket. The rear wheel is connected to the mounting bracket, and the mounting bracket is rotatably connected to the box body. The rear wheel assembly has an unfolded position and a retracted position, and the rear wheel assembly can move between the unfolded position and the retracted position. When the rear wheel assembly is in the unfolded position, the mounting bracket is inclined relative to the box body and forms a support frame for supporting the box body. When the rear wheel assembly moves from the unfolded position to the retracted position, the mounting bracket and the rear wheel assembly are retracted and installed in the storage chamber.

[0008] Beneficial effects: By rotating the lever assembly to drive the steering mechanism, which in turn drives the swivel wheels via a transmission component, this design makes the suitcase's steering operation more precise and flexible. Users can easily control the suitcase's direction of movement while riding or towing, adapting to various complex road conditions and turning needs, thus improving safety and convenience. Furthermore, the rear wheel assembly is movably housed within the storage compartment and can move between the unfolded and stowed positions. When not in use, the rear wheel assembly can be stowed into the storage compartment, restoring the suitcase to its traditional appearance and shape, making it easier to carry and store. For example, when traveling by plane or train, it can be placed on the overhead rack or under the seat without taking up excessive space. Attached Figure Description

[0025] This utility model discloses a rideable suitcase 100, such as... Figures 1-5 As shown, the luggage includes a case 10, a front wheel assembly 20, and a rear wheel assembly 30. The case 10 has an internal storage space 11 for accommodating luggage. The front wheel assembly 20 is located at the front of the case 10 and includes a pull rod assembly 21, a steering mechanism 22 connected to the pull rod assembly 21, and at least one swivel wheel 23. The swivel wheel 23 and the steering mechanism 22 are connected by a transmission member 40. The rear wheel assembly 30 is located at the rear of the case 10 and includes a rear wheel 31. The rear wheel 31 rotates to drive the luggage to move. At the same time, the steering mechanism 22 can be turned by rotating the pull rod assembly 21, and the swivel wheel 23 can be turned by the transmission member 40 to control the direction of movement of the luggage. The steering mechanism 22 is connected to the universal wheel 23 via the transmission component 40. The rotation of the pull rod assembly 21 synchronously drives the front universal wheel 23 to turn, allowing the user to complete flexible and precise steering control by operating the pull rod assembly 21. The rear wheel 31 drives the luggage to move, and the steering action of the front wheel assembly 20 makes the riding process smooth and comfortable, reducing the risk of tipping and slipping. The luggage of this utility model eliminates the need for users to pull or push by hand, reducing physical exertion, and is especially suitable for use in long-distance travel scenarios such as airports and train stations.

[0026] In this embodiment, as Figures 3-4 As shown, the omnidirectional wheel 23 is provided with a first transmission part 231, and the steering mechanism 22 is rotatably provided with a second transmission part 221. A transmission member 40 is wound around the first transmission part 231 and the second transmission part 221, thereby drivingly connecting the omnidirectional wheel 23 and the steering mechanism 22. Preferably, the transmission member 40 is a transmission belt with a ring structure. By winding the transmission member 40 around the first transmission part 231 and the second transmission part 221, a continuous wrapping force can be formed, ensuring the smoothness and synchronicity of the luggage compartment's turning action.

[0027] Specifically, the first transmission part 231 includes a first gear 232, the second transmission part 221 includes a first tooth 222, and the inner wall surface of the transmission member 40 is provided with a second tooth 41. The transmission member 40 is wound around the first transmission part 231 and the second transmission part 221, so that the second tooth 41 meshes with the first gear 232 and the first tooth 222, and the universal wheel 23 and the pull rod assembly 21 are connected by transmission through the transmission member 40. Through the above structure, a precise and reliable transmission system is formed, realizing the simultaneous bearing of multiple teeth, ensuring the synchronous rotation of the pull rod 211 and the steering of the universal wheel 23, so that the suitcase can achieve precise and reliable steering operation.

[0028] In this embodiment, the universal wheel 23 includes a connecting shaft 233 and a wheel body 234 rotatably connected to the connecting shaft 233. A first gear 232 is provided on the connecting shaft 233. The first transmission part 231 also includes a first bearing 235 disposed between the first gear 232 and the front bottom wall of the housing 10, and a second bearing 236 disposed between the first gear 232 and the wheel body 234. By providing the first bearing 235 and the second bearing 236, the frictional resistance between the first gear 232 and the connecting shaft 233 is effectively reduced, making the universal wheel 23 more flexible and stable when turning.

[0029] In this embodiment, a shim 237 is also provided between the second bearing 236 and the first gear 232. By providing the shim 237, the precise positioning between the first gear 232 and the second bearing 236 is achieved, avoiding axial misalignment or meshing failure, while also reducing the wear rate and improving the service life of the steering system of the entire front wheel assembly 20.

[0030] In this embodiment, the second transmission part 221 also includes a third bearing 223 sleeved on the tie rod assembly 21, and the third bearing 223 is located between the first tooth part 222 and the front bottom wall of the housing 10; by setting the third bearing 223, the rotation of the steering mechanism 22 is smoother, the friction between the rotating mechanism and the tie rod assembly 21 is reduced, and the service life of the front wheel assembly 20 is improved.

[0031] In this embodiment, there are two omnidirectional wheels 23, which are respectively installed on both sides of the housing 10. A first covering layer 238, which is a PU covering layer, is provided on the tires of the omnidirectional wheels 23. The two omnidirectional wheels 23 distributed on both sides of the housing 10 result in a more even distribution of the center of gravity, improved lateral support, and prevention of tipping, making riding more stable and safer. The PU covering layer 238 has excellent cushioning performance and can effectively absorb ground vibrations; at the same time, the PU material has low friction noise with the ground, improving the comfort of riding and towing.

[0032] In this embodiment, as Figures 4-5As shown, at least one first limiting block 224 is provided on the outer wall of the first tooth 222, and an active window 225 is formed between the first limiting block 224 and the tooth of the first tooth 222, allowing the transmission member 40 to pass through. With the above structure, the transmission member 40 is prevented from falling off or shifting due to vibration or impact during steering, thereby improving the reliability of the steering system.

[0033] In this embodiment, the rotating assembly includes a rotating seat 226 and an end cap 227 disposed at the bottom end of the rotating seat 226. A first tooth 222 is disposed on the outer side wall of the rotating seat 226, and the rotating seat 226 has a through channel 2261. The rotating seat 226 and the end cap 227 are connected by a first connector 2262 to form a first mounting cavity 2263 for connecting to the bottom end of the pull rod 211 of the pull rod assembly 21. At least one first mounting groove 2264 is disposed on the inner side wall of the rotating seat 226, and a mounting block 228 is fixedly connected in the first mounting groove 2264. The mounting block 228 is used to connect the rotating seat 226 and the pull rod 211. The end cap 227 is provided with... At least one first connecting portion 2271 is provided, at least one second connecting portion 2265 is provided on the rotating seat 226, and a third connecting portion 2281 is provided on the mounting block 228. A first connecting member 2262 is sequentially inserted into the first connecting portion 2271, the second connecting portion 2265, and the third connecting portion 2281, thereby fixing the end cap 227, the rotating seat 226, and the mounting block 228 together. Through this structure, the bottom end of the pull rod assembly 21 can be directly inserted into the first mounting cavity 2263 and fixed by the first connecting member 2262, preventing the end cap 227, the rotating seat 226, and the mounting block 228 from loosening during long-term vibration or frequent operation, thus enhancing the overall structural strength and durability. Preferably, the first connecting portion 2271, the second connecting portion 2265, and the third connecting portion 2281 are all screw holes, and the first connecting member 2262 is a screw. The screw connection provides a stable and reliable connection between the end cap 227, the rotating seat 226, and the mounting block 228.

[0034] In this embodiment, as Figure 5 As shown, a mounting protrusion 2282 is provided on the inner wall of the mounting block 228, and a mounting hole 212 is provided on the side wall of the pull rod 211. The mounting protrusion 2282 is installed in the mounting hole 212, so that the mounting protrusion 2282 and the pull rod 211 are fixedly connected. Through the above structure, a stable connection between the rotating seat 226 and the pull rod 211 is achieved, preventing the rotating seat 226 from falling off the pull rod assembly 21 when the pull rod 211 rotates.

[0035] In this embodiment, as Figure 6As shown, the front bottom of the housing 10 has a first cavity 12, on which a bottom cover 13 is provided. The first cavity 12 and the bottom cover 13 are connected by a second connector 14 to form a second mounting cavity 15 for mounting the front wheel assembly 20. The bottom wall of the first cavity 12 is provided with a plurality of connecting posts 121, and a fourth connecting part 122 is provided on the connecting posts 121. The bottom cover 13 is provided with a plurality of fifth connecting parts 131. The second connector 14 is sequentially inserted into the fifth connecting parts 131 and the fourth connecting parts 122, so that the bottom cover 13 is fixedly mounted on the first cavity 12. Preferably, the fourth connecting parts 122 and the fifth connecting parts 131 are both screw holes, and the second connector 14 is a screw. The bottom cover 13 is stably and reliably connected to the first cavity 12 by means of screw connection.

[0036] In this embodiment, a second mounting groove 123 and a third mounting groove 124 are also provided on the bottom wall of the first cavity 12. The universal wheel 23 is installed in the second mounting groove 123, and the steering mechanism 22 is installed in the third mounting groove 124 and is rotatably connected to the tie rod 211, so that the front wheel assembly has low friction and stable rotational support, improving transmission efficiency and service life. Furthermore, limit blocks 125 are provided on the outer walls of both ends of the third mounting groove 124, and several second limit blocks 2266 extend upward from the top upper edge of the rotating seat 226. The second limit blocks 2266 abut against the limit blocks 125 to limit the rotation angle of the rotating seat 226 and prevent structural interference or damage caused by excessive rotation.

[0037] In this embodiment, as Figure 2 As shown, a partition 16 is provided on the interior of the front side wall of the housing 10, forming a third mounting cavity 161 between the partition 16 and the front side wall of the housing 10 for mounting the pull rod assembly 21. By providing the partition 16, the pull rod assembly 21 is isolated from the housing 10, preventing dust, impurities and liquids from entering the pull rod assembly 21 and extending the service life of the pull rod assembly 21.

[0038] In this embodiment, as Figures 7-8 As shown, the pull rod 211 of the pull rod assembly 21 includes an outer pull rod 2111, an inner pull rod 2112 slidably disposed inside the outer pull rod 2111, and a handle 2113 connected to the top of the inner pull rod 2112. A button 2114 is provided on the handle 2113. The pull rod assembly 21 also includes a positioning member disposed inside the inner pull rod 2112. The positioning member is convexly connected to the button 2114. Pressing the button 2114 allows the inner pull rod 2112 to slide relative to the outer pull rod 2111. Releasing the button 2114 allows the inner pull rod 2112 to be positioned and installed in the outer pull rod 2111 by the positioning member.

[0039] Specifically, the positioning component includes a transmission rod 24 that is connected to the button 2114, and a positioning element connected to the bottom end of the transmission rod 24. The positioning element includes a mounting base 25 and a push rod 26. The push rod 26 is movably installed in the second mounting channel 251 in the mounting base 25 and connected to the transmission rod 24. The mounting base 25 is also provided with a third mounting channel 252. A positioning locking block 253 is slidably disposed in the third mounting channel 252. A communicating channel 254 is provided in the positioning locking block 253, and the communicating channel 254 is connected to the second mounting channel 251. The second mounting channel 251 is connected, and the push rod 26 passes through the second mounting channel 251 and extends into the connecting channel 254, so that the transmission rod 24 can drive the push rod 26 to move the positioning lock block 253 to lock or unlock the inner pull rod 2112 and the outer pull rod 2111; and an elastic reset member 255 is provided between one end of the positioning lock block 253 and the inner wall surface of the third mounting channel 252, and the other part of the positioning lock block 253 is also provided with a positioning protrusion 256 for connecting with the positioning hole 2115 on the side wall of the outer pull rod 2111.

[0040] In this embodiment, the push rod 26 has an inclined bottom surface 257, and the connecting channel 254 has an inclined inner wall surface 258 corresponding to the inclined bottom surface 257. When the button 2114 is pressed down, the transmission rod 24 drives the push rod 26 to move downward, and the positioning locking block 253 moves toward the inside of the inner pull rod 2112, so that the inner pull rod 2112 and the outer pull rod 2111 are unlocked. At this time, the elastic reset member 255 is compressed, and the inner pull rod 2112 and the outer pull rod 2111 are unlocked. The inner pull rod 2112 can slide on the outer pull rod 2111. When the button 2114 is released, the transmission rod 24 drives the push rod 26 to move upward, and the positioning locking block 253 moves toward the outside under the action of the elastic reset member 255, so that the positioning protrusion 256 passes through the positioning hole 2115 to fix the inner pull rod 2112 in the required position.

[0041] With the above structure, users can lock and unlock the inner pull rod 2112 and the outer pull rod 2111 with just one hand by pressing button 2114, without the need for two hands or complicated operation steps, which greatly improves the convenience of use. In addition, the positioning protrusion 256 on the positioning lock block 253 is connected to the positioning hole 2115 on the side wall of the outer pull rod 2111, which can accurately fix the inner pull rod 2112 in the required position, preventing the inner pull rod 2112 from sliding freely relative to the outer pull rod 2111 during use, ensuring the stability of the pull rod assembly structure, thereby ensuring the safety of the entire device, such as a suitcase, that uses the pull rod assembly during movement.

[0042] Preferably, the positioning component also includes an auxiliary component 27 connected to the mounting base 25. The bottom end of the auxiliary component 27 abuts against the inner wall surface of the end cover, and an elastic element 28 is provided between the bottom end of the auxiliary component 27 and the inner wall surface of the end cover. When the button 2114 is released, the auxiliary component 27 will push the inner pull rod 2112 upward under the action of the elastic element 28. With the above structure, when adjusting the length of the pull rod, the user does not need to manually pull the inner pull rod 2112 upward with great effort. Especially when the inner pull rod 2112 is heavy or the user's hand strength is weak, the automatic rebound function greatly reduces the operating burden, making the adjustment of the pull rod easier and more convenient, and improving the user experience.

[0043] In this embodiment, as Figures 1-2 as well as Figures 9-10 As shown, a storage chamber 110 is also provided at the rear bottom of the housing 10. The rear wheel assembly 30 is movably disposed in the storage chamber 110. The rear wheel assembly 30 includes a rear wheel 31 and a mounting bracket 32. The rear wheel 31 is connected to the mounting bracket 32, and the mounting bracket 32 ​​is rotatably connected to the housing 10. The rear wheel assembly 30 has an unfolded position and a retracted position, and the rear wheel assembly 30 can move between the unfolded position and the retracted position. When the rear wheel assembly 30 is in the unfolded position, the mounting bracket 32 ​​is inclined relative to the housing 10 and forms a support frame for supporting the housing 10. When the rear wheel assembly 30 moves from the unfolded position to the retracted position, the mounting bracket 32 ​​and the rear wheel assembly 30 are retracted and installed in the storage chamber 110.

[0044] In this embodiment, as Figures 11-12 As shown, the mounting bracket 32 ​​includes a first bracket 321 and a second bracket 322 rotatably connected to the first bracket 321. The first bracket 321 is fixedly mounted on the rear side wall of the case 10. The rear wheel 31 is connected to the second bracket 322. A first connecting rod 3211 is rotatably mounted on the first bracket 321, and a second connecting rod 3221 is rotatably mounted on the second bracket 322. The first connecting rod 3211 and the second connecting rod 3221 are rotatably connected by a first pivot 323. When the rear wheel assembly 30 is in the unfolded position, the second bracket 322 rotates relative to the first bracket 321, forming a support frame with a triangular structure with the first connecting rod 3211 and the second connecting rod 3221. By forming a triangular support frame, the suitcase has more stable and reliable support when unfolded, especially providing solid support for the suitcase when riding or stationary, significantly improving overall balance and safety.

[0045] In this embodiment, a first connecting hole 3212 is provided on both end sidewalls of the first connecting rod 3211, and a second connecting hole 3222 is provided on both end sidewalls of the second connecting rod 3221. The second connecting rod 3221 is sleeved on the first connecting rod 3211, and a first pivot 323 is sequentially inserted into the second connecting hole 3222 and the first connecting hole 3212, extending outward to form a first extension end 3231. A first stop 3232 is provided on the first extension end 3231 to prevent the first connecting rod 3211 and the second connecting rod 3221 from detaching from each other. This structure ensures a stable and reliable rotatable connection between the first connecting rod 3211 and the second connecting rod 3221.

[0046] In this embodiment, a movable pull block 3223 is rotatably mounted on the second bracket 322, and the movable pull block 3223 abuts against one end of the second connecting rod 3221. When the movable pull block 3223 is pulled outward, one end of the movable pull block 3223 pushes the second connecting rod 3221 to move, thereby pushing the second bracket 322 to rotate relative to the first bracket 321, so that the rear wheel assembly 30 can move between the unfolded position and the retracted position. By setting the movable pull block 3223, the rear wheel assembly 30 can quickly switch between the unfolded position and the retracted position without the need for additional tools or cumbersome actions, thus improving the user experience.

[0047] Preferably, the top ends of the first bracket 321 and the second bracket 322 are rotatably connected by a second pivot 3233, and both the top side walls of the first bracket 321 and the second bracket 322 are provided with connecting holes. The second pivot 3233 passes through the connecting holes and extends outward to form an extension end. The extension end is provided with a stop to prevent the first bracket 321 and the second bracket 322 from falling off each other. In addition, in this embodiment, the first connecting rod 3211 and the first bracket 321 are rotatably connected by a third pivot 3234. The movable pull block 3223, the second connecting rod 3221 and the second bracket 322 are rotatably connected by the third pivot 3234. When the movable pull block 3223 is pulled, the movable pull block 3223 rotates around the third pivot 3234 and lifts the second connecting rod 3221 upward, so that the second connecting rod 3221 rotates around the first pivot 323, and at the same time drives the first bracket 321 to rotate relative to the second bracket 322, so as to move the rear wheel assembly 30 to the storage position. In this embodiment, the second pivot 3233 and the third pivot 3234 have the same structure. Preferably, a fourth pivot 3235 is also provided between the movable pull block 3223 and the second support 322.

[0048] Preferably, there is only one rear wheel 31. A single rear wheel 31 can respond to torque changes more quickly, improving the overall steering sensitivity and handling, making it easier and more comfortable for users to push or tow. The rear wheel 31 has a rear wheel cover layer 324, which is a PU rear wheel cover layer 324. The PU rear wheel cover layer 324 has good elastic cushioning, effectively absorbing impact vibration and reducing driving noise, thus improving the quietness of pushing and pulling.

[0049] In this embodiment, as Figures 11-13 As shown, the rear wheel assembly 30 also includes a locking mechanism for locking or releasing the rear wheel 31 in the storage chamber 110. The locking mechanism includes a first locking block 325 disposed on the first bracket 321 and a second locking block 326 disposed on the second bracket 322. The first locking block 325 is disposed on the inner wall of the first bracket 321 and has a locking groove 3251. The second locking block 326 is slidably disposed in the mounting groove 3224 of the second bracket 322. The rear wheel assembly 30 is provided with a locking buckle 3261. The second locking block 326 has a first position and a second position, and the second locking block 326 can move between the first position and the second position. When the rear wheel assembly 30 is in the retracted position, the second locking block 326 is pushed from the first position to the second position, so that the locking buckle 3261 is located above the locking groove 3251. The second locking block 326 is pushed again from the second position to the first position, so that the locking buckle 3261 falls into the locking groove 3251, thereby locking the rear wheel assembly 30 in the retracted position. With the above structure, the rear wheel assembly 30 can be firmly locked in the storage chamber 110, effectively preventing the rear wheel assembly 30 from accidentally unfolding due to shaking or bumping during luggage transportation or movement, ensuring the stability of the storage state. Moreover, the user only needs to push the second locking block 326 to move between the first position and the second position to lock and release the rear wheel assembly 30. The operation is simple and does not require complicated tools or professional skills, making it convenient for users to quickly operate the rear wheel assembly 30 in different scenarios.

[0050] In this embodiment, a sliding groove 3225 is provided at the bottom of the mounting groove 3224, and a slider 3262 is provided on the second locking block 326. The slider 3262 is slidably disposed within the sliding groove 3225, allowing the second locking block 326 to move between a first position and a second position. A limiting step 3263 is provided within the mounting groove 3224 to limit the movement distance of the second locking block 326, and at least one limiting protrusion 3264 is provided on the inner wall of the first locking block 325. A limiting groove 3265 is provided on the first bracket 321 to receive the limiting protrusion 3264, and the limiting protrusion 3264 can slide within the limiting groove 3265. Through the above structure, the movement of the first locking block 325 between the first position and the second position is more stable and smooth, avoiding jamming and offset during the movement process, and ensuring the reliability of the locking mechanism operation.

[0051] In this embodiment, a wheel fork 3226 is provided at the bottom of the second bracket 322. The rear wheel 31 is rotatably connected to the wheel fork 3226 via a wheel axle 3227. The rear wheel 31 has an internal mounting channel 311, in which a motor 312 is installed. The motor 312 is electrically connected to a power supply device (not shown) inside the case 10. The motor 312 rotates to drive the rear wheel 31 to rotate. The motor 312 is a brushless motor. This structure ensures the flexibility of the rear wheel 31 during rotation and makes the connection between the rear wheel 31 and the bracket firm and reliable. In addition, the use of a brushless motor 312 reduces noise during the movement of the suitcase, and the brushless motor 312 has a longer service life, reducing the frequency of maintenance and replacement and lowering the operating cost.

[0052] In this embodiment, the storage chamber 110 includes a first storage chamber 111 and a second storage chamber 112 communicating with the first storage chamber 111. The mounting bracket 32 ​​is movably disposed in the first storage chamber 111, and the rear wheel 31 is movably disposed in the second storage chamber 112.
